Beyond Jupiter, The World of Distant Minor Planets: (341520) Mors-Somnus

JOA 2022, Vol. 12, No. 4, Page 18

Author(s): Konrad Guhl

Abstract: The minor planet (341520) Mors-Somnus was discovered in 2007 and with an orbital period of 248 years, is in resonance with Neptune and so belongs to the Plutino class of trans-Neptunian objects. The elliptical orbit has its perihelion just inside the perihelion distance of Neptune. It was found to be a double asteroid, with each body having approximately the same size, roughly 120 km across.
